Question

In solvents like DMSO, acetonitrile, F- ion of dissolved NaF is more reactive than in methyl alcohol because (A) CH3OH is more polar than DMSO and CH3CN (B) CH3OH is less polar than DMSO and CH3CN (C) unsolvated F- ion is DMSO or CH3CN acts more efficiently as nucleophile (D) -OH group is a better leaving group than F- ion

Tardigrade Admin · Accepted Answer

In methyl alcohol, F- ion is solvated but in DMSO or CH3CN (aprotic solvent) F- ion is not solvated. Unsolvated F- ion acts more efficiently as a nucleophile.

Q. In solvents like $D MSO$ , acetonitrile, $F^{-}$ ion of dissolved $N a F$ is more reactive than in methyl alcohol because

$C H_{3} O H$ is more polar than $D MSO$ and $C H_{3} CN$

$C H_{3} O H$ is less polar than $D MSO$ and $C H_{3} CN$

unsolvated $F^{-}$ ion is $D MSO$ or $C H_{3} CN$ acts more efficiently as nucleophile

$- O H$ group is a better leaving group than $F^{-}$ ion

In methyl alcohol, $F^{-}$ ion is solvated but in $D MSO$ or $C H_{3} CN$ (aprotic solvent) $F^{-}$ ion is not solvated. Unsolvated $F^{-}$ ion acts more efficiently as a nucleophile.

Q. In solvents like DMSO, acetonitrile, F− ion of dissolved NaF is more reactive than in methyl alcohol because

CH3​OH is more polar than DMSO and CH3​CN

CH3​OH is less polar than DMSO and CH3​CN

unsolvated F− ion is DMSO or CH3​CN acts more efficiently as nucleophile

−OH group is a better leaving group than F− ion
